AI overview

Polonium is a rare, highly radioactive chemical element (symbol Po, atomic number 84) with no stable forms, making it chemically similar to selenium and tellurium but with some metallic properties. Because all of its isotopes decay quickly, polonium is found only in tiny traces in nature, primarily as polonium-210 in uranium ores where it forms as part of uranium's decay process.
